Science:

”Archaeopteryx probably cannot tell us much about the early origins of feathers and flight in true protobirds because ARCHAEOPTERYX WAS, IN A MODERN SENSE, A BIRD.” (Hanegraaff, Fatal Flaws "What Evolutionists Don't Want You To Know", W Publishing Group, 2003, p. 19)

-    It is a mosaic animal with teeth and claws. Two bird species living today, the touraco and the hoatzin, have claws which allow them to hold onto branches. Other toothed-birds are also known to have lived in the same period.

-    The tooth structure of Archæopteryx and other birds with teeth is totally different from that of their alleged ancestors, the dinosaurs. The teeth of theropod dinosaurs, the alleged ancestors of these birds, had serrated teeth with straight roots.

-    These researchers also compared the wrist bones of Archæopteryx and their alleged ancestors, the dinosaurs, and observed no similarity between them.

-    They formerly claimed that there was no breast bone under the chest cavity for the muscles needed for flight to attach to. But the seventh Archæopteryx fossil, discovered in 1992, did have a breast bone. This entirely does away with all claims that the animal could not fly.

-    Archeopteryx’s asymmetrical feather structure, identical to that of today’s birds, shows that it was capable of perfect flight.

LIAONINGORNIS

Paleontologist Robert Carroll

The geometry of the flight feathers of Archæopteryx is identical with that of modern flying birds, whereas nonflying birds have symmetrical feathers. The way in which the feathers are arranged on the wing also falls within the range of modern birds… According to Van Tyne and Berger, the relative size and shape of the wing of  Archæopteryx are similar to that of birds that move through restricted openings in vegetation, such as gallinaceous birds, doves, woodcocks, woodpeckers, and most passerine birds… The flight feathers have been in stasis for at least 150 million years (Robert L. Carroll, Patterns and Processes of Vertebrate Evolution, Cambridge University Press, 1997, p. 280-81)

-    Archaeopteryx's ear structure: A. D. Walker studied the ear structure of Archaeopteryx and stated that it was the same as that in present-day birds

-    Archaeopteryx's wings: J. Richard Hinchcliffe of the University of Wales Biological Sciences Department used modern isotopic techniques in his study of embryos and established that the three dinosaur digits on the forelimbs are I-II-III, whereas bird wing digits are II-III-IV. This is a major difficulty for the proponents of the so-called Archaeopteryx-dinosaur link.  Hinchcliffe's research and observations were carried in the famous magazine Science in 1977

-    The Theropod dinosaurs suggested as the ancestors of Archaeopteryx are actually younger than it.

-    Most important of all, IS THE EXISTENCE OF PERFECT FLYING BIRDS THAT LIVED IN THE SAME PERIOD AS ARCHÆOPTERYX. The 140-million-year LIAONINGORNIS and the 120-million year CONFUCIUSORNIS.
